The MR33 motor pinions are one of our absolute bestsellers!
The pinions are characterized by perfect concentricity and are extra hard-coated for a long service life.
A grub screw for mounting the pinion on the motor shaft is also included.
Our MR33 motor pinions are available with 48DP and 64DP teeth. Simply select your desired number of teeth in the drop-down menu!
 
Pro tip: It's always worth experimenting with different sprockets. In all classes where the final reduction ratio is not fixed, you should always have different ratios in your pocket to be able to react to different race tracks. Calculate the total gear ratio of your RC car as follows: Divide the number of teeth of your main gear by that of your motor pinion, and then multiply this by the internal reduction ratio of your model (see building instructions). 
 
Formula: Main gear / motor pinion x internal gear ratio = total gear ratio
